AUTOMOBILE-LOCK Specication of Letters Patent.

Patented Nov. 24, 1,914.

Application led January 24, 1914. Serial No. 814,037.

To all Iwhom it may concern Be it known that I, PAUL R. POHLER, a subject of the Emperor of Germany, reslding at Detroit, in the county Aof Wayne and State of Michigan, have invented certaln new and useful Improvements in4 Automobile-Locks, of which the following is a specification, reference being had therein to the accompanying drawings. i

This invention relates to an automob1le lock, and the primary object of my invention is to provide a steering post 4with a novel lock for holding the steeringrod or shaft whereby the steering mechanism-of the automobile cannot be operated, thereby precluding any possibility of the automobile being stolen or surreptitlously used.

A further object of my invention is to provide a strong and durable key operated lock mechanism that is easy to install and highly efficient for the purposes for which l it is intended.

I accomplish the above and other `results by a mechanical construction that will be hereinafter specifically described and then claimed, and reference will now be had to the drawing, wherein Figure 1 is a side elevation of a portion of an automobile provided with my improved lock; Fig. 2 is an enlarged longitudinal sectional view-of the lock showing the \bolt in a retracted position; Fig. 3 is a perspective view of the bolt of the lock; Fig. 4 is an end view of the lock showing a catch; Fig.. 5 is a longitudinal sectional view of the lock oasing showing the lock mechanism in elevation and the bolt extended; Fig. 6 is a longitudinal sectional view of the lock showing the bolt in an extended osition; Fig. 7 is a horizontal sectional view of the lock; Fig. 8 is a side elevation of a portion of a lock, and Fig. 9 is al cross section of the same taken on the line IX-IX of Fig. 2;

To use my lock in connection with a steering post, it is only necessary to provide a tubular steering post 1 with a slot 2 and the steering rod or shaft- 3 within the post with a recess 4 adapted to register .with the slot 2.

Mounted or otherwise secured uponl` the tubular steering post 1 over that portion' of the post having the slot 2 isa sleeve 5 provided with a rectangular lock casing 6 that extends radially from the side of the post 1' provided with the slot 2. The inner end 'wall 7 of casing' provided with Aa slot 8 of less length than the slot 2, thereb providing' shoulders 9, the urpose of whic will presently appear. the casing 6 is formed with bosses 10 to receive screws 11 or other fastenin means employed for retaining a detacha le 'end wall or lid 12 in engagement with the casing 6.

Arranged within the casing 6 is a box like shell 13 having a detachable front'wall 14. The front wal 14 has a key slot 15 and adapted to register with the slot is a similar slot 16 in a revoluble key plate 17 loosely mounted in an openin 18 providedtherefor in the front wall of t e casingl 6. The key plate 17 is of the ordinary and well known type and is retained Within an opening .18 inthe detachable front wall 14 b the peripheral flanged inner edge of the ey plate. T e rear wall of the shell 13 has an o ening 19 registering with an opening'20 1n the rear wall of the casing 6, said openings accommodating the end of a key 21 lnserted in the lock, as besttshown in Fi 9. The inner end of the shell 13 is provi ed with a guide slot 22 registering with the slot 8 in the casing 6 and slidably mounted in' the slot 22 is a bolt 23 adapted to enter the recess "4 of the steering rod or shaft 3 and prevent said rod or shaft from being rotated relatively to the tubular post .1. {Pheouter T e outer end of end of the bolt 23 has a crosshead 24 that engages the top and bottom walls vof the d shell 13 and coperates with the walls of the slot'22 in guiding a longitudinal movement of the bolt 23 within said shell. The

same end of the bolt has a boss 25 and de tachably mounted in said boss is the inner end of a push rod or pin 26, which extends through an opening provided therefor in the detachable end wall or lid 12 of the casing 6. The outer end of the push rod or pin is provided with a button 27 to facilitate shifting the bolt within the shell 13.I The bolt is held normally retracted by coiled re- \tracti1e springs 28 arranged -atthe sides of bolt, as at 29 and to the end wall of the shell Vthe push rod or pin 26 and connected to the l los key openingl and a longitudinal vertical*l latchslot 32 of opening 31. Pivotally mounted in the slot 32 by transverse pins 33 are opposed latches 34 having hooklshaped ends 35v adapted to greater length than the key 'lrey are brought into en..n

engage the shoulders retain the bolt 23 in :best shown 1n Fig.

n36 mounted in sloty the hook- Vshaped ends 35 oit thelatohes 3l and holds the ends of the latches in an estended po:- sition. To retract the hooloshap ends of the latches the key 2l is inserted l the lool; and diametrically opposed bits 37 oit said ment with the concave confrontine,= sides` latches.

'lo hold the bol tion with the relatively the s ot tumblere are as ,f

preferably eight in ar ranged in sets tv.' are.

nivota'lly 'mounted r transferee pins carried by theside n olj the shell i3 said tuinblers have tao ends thereof provided with bayont-tsshaned slots Il@ into which extends angle lee fl By providing the bo 32, the central por f tour walls, as best shown ir lugs ll are "formed i ith the evolver and lower edges ol' said Walls extend at right angles thereto into the bayonetshaoed slots 40 of 'the et tumblers. The' tumblers 38 extend into the slots 32 and are held in the 'path of bits l2 oit the key by llat compression springs 43 carried by the Walls of the shell lh lllhen a hey ci" "he proper shane is insorted in the loch and rotatedY the hookshaped ends 35 of the latches 3are tracted and sinieltaneous with the shitting; of the latches del the tmnblers 3S are shoved to place the longitudinal `portions of slots l0 in alinemen't with the lugs al, whereby the springs 28 can retract the bolt and thus release the steering rod or shaft 3 relatively to the tubular steering1 post l.

"When itis desired to lock the steering` rod or shaft 3 it isonly necessary to 'push in ivardly upon the button 2l', de beveled edges of the. hook-shaped ends 35 olf the latches 3l cause said latches to recede as the hook-shaped ends thereof engage the Walls of the slots 22 and 8 immediately upon the bolt Q3 reaching" an extended position the latches are released to engage the shoulders 9 and lock the bolt 23. By this time th'e angle lungs 4l of the bolt are located in the inner ends of the slots l0 ot the tumblers, and even though the detachable ond ivall or lid l2 be removed, it is impossible to Wi l draw the shell 13 tron "5.o casina' '5 until a key of proper shane is the look to aotuate the vtuniblers and latches thereof. 'lo prevent the bolt oli the loelr from being accidentally actuated While an automobile is beinefdriven, a small catch is oivotallv mounted upon-tho lid olf the casing o to `e slots 3l and vbolt pres-ents ig. 5 and the r-ldnvther description,
